摘要: Far-red (FR) light regulates phytochrome-mediated morphological and physiological plant responses. This study aims to investigate how greenhouse tomato morphology and production response to different durations of FR light during daytime and at the end of day (EOD). High-wire tomato plants were grown under intra-canopy lighting consisting of red (peak wavelength at 640 nm) and blue (peak wavelength at 450 nm) light-emitting diodes (LEDs) with photosynthetic photon flux density (PPFD) of 144 mu mol m(-2) s(-1) at 10 cm away from the lamps, and combined with overhead supplemental FR light (peak wavelength at 735 nm) with PPFD of 43 mu mol m(-2) s(-1) at 20 cm below the lamps. Plants were exposed to three durations of FR supplemental lighting including: 06: 00-18: 00 (FR12), 18: 00-19: 30 (EOD-FR1.5), 18: 00-18: 30 (EOD-FR0.5), and control that without supplemental FR light. The results showed that supplemental FR light significantly stimulated stem elongation thereby resulting in longer plants compared with the control. Moreover, FR light altered leaf morphology toward higher leaf length/width ratio and larger leaf area. The altered plant architecture in FR supplemented plants led to a more homogeneous light distribution inside the canopy. Total plant biomass was increased by 9-16% under supplemental FR light in comparison with control, which led to 7-12% increase in ripe fruit yield. Soluble sugar content of the ripe tomato fruit was slightly decreased by longer exposure of the plants to FR light. Dry matter partitioning to different plant organs were not substantially affected by the FR light treatments. No significant differences were observed among the three FR light treatments in plant morphology as well as yield and biomass production. We conclude that under intra-canopy lighting, overhead supplemental FR light stimulates tomato growth and production. And supplementary of EOD-FR0.5 is more favorable, as it consumes less electricity but induces similar effects on plant morphology and yield.
